' CARIBURETER.

) To aZZ whom it may concern Be it known that I, HENRY M. REIOHEN- neon,a citizen of the United States, residing at Rochester, in the county ofMonroe and State of New York, have invented cerr, new and usefullmprovementsin Carburetors; and 1: do hereby declare the following to afull, clear, and exact description oi the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in carburetors and 1t consists inthe constructions, comblnatlons and arrangements herea in described andclaimed.

An ob ect of my invention is to provide provide an improved carbureteradapted to. supply and mamtam a Iuel m a hnely cm minuted condition.

A further object of my invention is to provide improved carburetors forinternal combustion engines which will operate effectually to preventdeposition or accumulari the fuel therein under all varying e1 viceconditions, thereby insuring auni- Iorm and efiicient mixture at alltimes.

in the accompanying drawings, forming a part of t is application and inwhich similar reference symbols indicate corresponding parts in theseveral views :Figure 1 is a side elevation, partly in section,illustrating one embodiment of my invention; Fig. 2 is a plan of theconstruction shown in Fig. 1 Fig. 3 is a section through Fig.1; Fig. 41s a section through Fig. 2; and Fig. 5 is a section on the line 55 ofFig. 1.

inferring to the drawings :'1 indicates a. rectangular inlet conduitconnected to a usual manifold 2 provided with intakes 3 to the cylindersof an internal combustion engine; said-conduit being provided with athrottle valve 4 adapted to be manually or automatically actuated in anyusual manner.

'iin in erted siphon 5 has one end 6'freely open to the atmosphere, andits other end extending; within said conduit 1 to constitute a fuelchamber 7 provided with apertures 8. An air supply pipe 9 is secured tothe conduit 1 and provided with a series of mpples 19 dischargingthrough said fuel chamber? coaxially with the apertures 8; the admissionof air to said pipe 9 being controlled Specification of LettersPatent.

by a ported valve .11 rotatably mounted therein.

. A fuel feed pipe 12 i'sprovided for: Cong.

ducting fuel from the usual float t'ankto av head 13 7 provided with acylindrical bushing provided with a rectangular port 16 adapted tocooperate with a, similar port-l7 1n said bushmg. A spring 18 isconfined between said head 13 and a collar 19 on said I valve foryleldingly maintaining the lattel-depressed in closedposition, as shownin Fig. 1. The valve 15 is provided with a pin or lug 20 in engagementwitha cam rall 21 which latter is carried by a bracket 22; said bracketbeing adjustably'secured to the conduit 1 by'lscrews 23 extendingthrough arc-shaped slots ,24 in said bracket concentric with thevalve15.'

A rectangular air inlet valve 25 is pivotally mounted within the conduit1 between the throttle valve 4 and fuel-chamber 7 in position to beactuated by the suctionot the engine for directingthe indrawli airacross the apertures 8 of said chamber.

A link 26' is suitably connected, as by ball and socket joints 27 and 28to cranks 29 and 30 on the feed valve 15 and inlet valve spindle 31;said link being provided'with adjusting means, such as a turn buckle 32.The other end of the e'duction valve spindle 31 carries a crank 33,which is connected to a crank 34 on the valve 11 of the air pipe 9 by alink 35 provided with a turn buckle 36. This provides a simple andadvantageous means by which the fuel feed valve 15 and air valve 11' aresimultaneously actuated by the suction of the engine; the degree of suchactuation being proportionate to the extent of opening of the inletvalve 25 at all times.

The manifold 2, which constitutes a portion of the inlet conduit for theengine, is provided with a converging end nozzle 37 connected by a pipe38 with a point in the fture to sweep by its kinetic energy throughtakes 3 or by stoppage of the engine. This provides a highlyadvantageous action, by

which alliresidual or surplus fuel will be carried into the by-pass 38,and all danger of troublesome deposition and accumulation of fuel in theinlet conduit will be eliminated,-thereby insuring an: eiiicient mixtureunder all operative conditions. 7

A U-tubef40 has one leg extending from the bottom of the by-passfordraining by gravity any fuel condensed within said by pass. The otherleg gtlof said U-tube opens within the discharge end of said bypass andhas an atomizing air tube 42 communicating therewith, said leg and tube42 being connected wlththe air supply pipe 9 by'a pipe 4-2. The upperend of the leg of the U-tube is shown closedby a screw 2, which providesmeans for convenient access in cleaning. This provides a simple andefficient means by which any fuel condensed in the by-pass 38, which isnot reevaporate'd'by the heating; jacket 39 thereof, will collect in theU-tube 40 and be sprayed from said tube into, the inlet conduit by theinjector action of the air drawnthrough tube Y42 and pipe 42 by theengine suction. This insures an efficient admixture of the fuel andprovides an advantageous supply of fuel in starting the engine.

If desired, the supply pipe 9 can be readily connected to a source ofcompressed air 9 for starting; this is especially advantageous whenemploying a heavy fuel. I

As the result of extensive experiment, I have discovered that the fineparticles of a fuel which has been reduced to a nebulized condition by astrong atomizing action tend to repel one another, and that suchrepelling force acts to maintain the particles separated in thenebulized state. In order to advantageously utilize this action, Ipreferably line or coat the interior of the inlet "conduit with amaterial which is insoluble and immiscible, Wltlltllltl also, in a senserepel'lanttothe fuel, the particles of fuel and the coating specifiedhaving probably become charged with'static electricity ofa potentialdifferent from that. of the nebulized fuel, I-have found that such acoating of shellac acts to m nimize the accumulation 'of-fuel on theconduit walls probably because of the smooth surface and oil repellentnature of theshellac coating; such ac tion is advantageously obtainedwith cast iron manifolds by employing a lining of porcelain or glass,which further tends to reduce surface adhesion. The friction of the fuelparticles upon the walls of "the con- 'duit, especially when, as isoften the ease,

the air current 'assumcsa helical or gym-v he affected by the fuel.

This novel construction insures'the maintenance of a uniform combustiblemixture within the inlet conduit and delivers the fuel directly to theengine in a finely divided and intimately admixed condition; therebyinsuring a maximum efliciency and economy of op eration.-

The inverted siphon pipe 5 is surrounded Y by a removable casing 43having an inlet pipe 44 and outlet pipe is for the circulatiouof asuitable heating medium therein, thereby providing means for efficientlyheating and vaporizing the fuel fed to said pipe 5. i

I have illustrated" and described preferred and satisfactoryconstructions, but changes may be made within the spirit and scope of myinvention.
